Customer Question

I have a 1993 Nissan 240sx with a stock ka24de. Motor has been rebuilt and runs good. I get a CEL code 32. EGR was tested all parts work after replacement of EGR-BPT. A mechanic I consulted said intake manifold is a little clogged, resulted in limited flow in EGR path. Mechanic says to clean is a big 2day job. Another mechanic said to unscrew this nickel-size plug and spray with cleaner and use wirebrush.
Will this work? Does the intake have to be removed from the engine? Is there a simpler way? How much is fair price for this cleaning service? Is it easier to buy used and cleaned intake?

Nickel-sized plug in on intake manifold and seems to run front to back of intake, lining up with EGR valve.

You do not need to remove the intake. I would remove the EGR and then remove the plugs and use Throttle Chamber cleaner and a wire brush to clean the intake and blow it out where the EGR is mounted.
